While 2 ohm ratings with big power are everywhere in marketing, it can be seen here that to truly deliver significant continuous power into 2 ohms takes huge current, it takes almost the full capacity of a 20 amp mains circuit to do it on one channel. It is even more of a challenge to do this in a high fidelity linear amplifier.

Fortunately, Audio is not a continuous draw, so we can time share a 2500 watt power supply between two channels with the help of 88000 uF energy storage.

However, every power unit itself is built to withstand its full rating 100% continuous for the benefit of reliability and longevity. How do competitors claim double this power with a 15 amp mains breaker ?

Its Simple, a 1/8 duty Cycle = (12%) of real power, enforced by compression and other limiting circuits.

This can be verified by looking at service manuals for popular brands and locating the VCA circuit in the input stage.

The result is a product that can produce very loud bursts, but not hold up on a long note.

General Specifications:

Frequency response as controlled by input preamp:
10hz – 60khz within 0.5 dB full power

Frequency response of power unit without preamp or output choke:
10hz – 100khz within 0.5 dB full power

These specifications are by design. The use of large amounts of negative feedback to obtain vanishing THD and higher damping is easy to do, but blind listening tests have proven that low feedback designs sound more natural and less fatiguing.

Tests are real world full power and bandwidth, and not selected sweet spots
in the operating range.
